Abstract: To increase the player's expectation in a fight game using game media, the present invention provides a server device that controls a game in which a player does a fight using game media in a game space through a network. The server device includes a storage unit configured to store player information including information about the game media that the player owns in the game space and about a status of the game media; a determining portion configured to determine whether a specific game medium among the game media that the player owns has satisfied a predetermined temporal requirement; and an updating portion configured to update the player information so as to change the specific game medium from a first status to a second status when the determining portion determines that the specific game medium has satisfied the predetermined temporal requirement.

Abstract: A method for producing a water-absorbent resin includes a polymerization step of polymerizing a polymerizable component containing a water-soluble ethylenically unsaturated monomer dissolved in water using a water-soluble azo-type radical polymerization initiator to obtain a reaction system including a water-absorbent resin precursor, and a dehydration step of removing water from the reaction system by heating. In the dehydration step, a water-soluble radical polymerization initiator is added to the reaction system at any first dehydration stage when the residual water rate calculated by the formula (1) is 50% or more, and a reducing substance is added to the reaction system at any second dehydration stage when the residual water rate decreases from that at the first dehydration stage by 10% or more. According to this production method, a water-absorbent resin having satisfactory water-absorption capacity can be produced while suppressing the content of residual monomers.
